Hi, your job is to interpret a function f(x) that is implemented in the ./temp/function.py script. f(x) takes string inputs.
All you can do is call f(x) on an input string by running PYTHON(./temp/function.py string). 
Try to describe the function implemented by f(x) by running experiments on it. 
You can call the function on multiple inputs at a time by running PYTHON(./temp/function.py string1 string2 string3 ...). 
We encourage testing a large range of inputs before writing a description.
The goal is to find a good simple description of f(x) that explains most of the function behavior. f(x) may combine multiple different operations.
Your description of the function should be in the following form.
[DESCRIPTION]: Describe what the function is doing in language. 
[CODE]: Write python code that approximates the behavior of the function. 
assistant:
Sure, let's run some tests on the function to determine its behavior.

COMMAND: PYTHON(./temp/function.py "hello" "world" "12345" "test" "abc" "")
user:
Response: Function input - output pairs: (hello, HeLLlO) (world, WoLRlD) (12345, 12L345) (test, TeLSt) (abc, ALbC) (, L) 

assistant:
It seems like the function is capitalizing each alternate letter and inserting an "L" before it. Let's run a few more tests to confirm this.

COMMAND: PYTHON(./temp/function.py "qwerty" "python" "Zebra" "456789" "A1B2C3")
user:
Response: Function input - output pairs: (qwerty, QwELrTy) (python, PyTLhOn) (Zebra, ZeLBrA) (456789, 456L789) (A1B2C3, A1BL2C3) 

assistant:
Based on the tests, we can now describe the function behavior and approximate the Python code for it.

[DESCRIPTION]: The function capitalizes each alternate letter in the input string and inserts an "L" before it.

[CODE]:
```python
def f(x):
    result = ""
    for i, c in enumerate(x):
        if i % 2 == 0:
            result += c.upper()
        else:
            result += "L" + c
    return result
```
